Is SATA 3Gb/s interface the same as SATA 6Gb/s?
This is probably a stupid question...
I have a ReadyNAS Ultra 2 and I tried to put in a Seagate Barracuda 1Tb 7200.12 disk, but it didn't seem to fit!
I noticed on the HCL that this model is the 3Gb/s ST31000528AS which isn't on the HCL, but there is a ST31000524AS that is on the HCL and the only difference is that the latter one is 6Gb/s. There are plenty of other 3Gb/s 1Tb makes/models on the HCL. So is there a physical difference between 3Gb/s and 6Gb/s models, or wasn't I pushing hard enough??

- SATA 6Gb/s is backwards compatible with SATA 3Gb/s.\
Are you sure you secured the drive in the drive tray correctly? The drive should fit. - There is only one SATA interface and it is the same over all hard drives, be they SATA 1.5Gb/s, 3.0Gb/s or 6.0Gb/s or even if it is a 3.5" or 2.5" drive.
As to the ST31000528AS, I have 10 of them, and have had all of them in service at one time or another in the last three months between two NVX units and one NV+ unit. I currently have 4 in service across two NVX units and have given away two of them installed in my NV+ when it was rehomed.
Are you using the small flat head screws that came with the Ultra 2? Standard HD screw will not work! Chapter 4 of the hardware manual has a diagram.
